I have three MacOSs, and set different names for User and Home Folder. I take Emacs as my default editor in those devices.

Using Emacs to edit tex-document, I found the code \input{~/Documents} and \input{$HOME/Documents} can't work when compiling, Error message said not found such file. To make it work, I must write the absolute path, such as \input{/Users/Abel/Documents} .

The trouble is due to the different account names and home folders in the three devices, I don't want to alter them into a same name. Q: Is there any method that keeping the situation and Emacs can recognize \input{~/Documents} or \input{$HOME/Documents} ?

Here are some extra information:

  1. Use other editors, such as TeXShop, this trouble doesn't happen both \input{~/Documents} and \input{$HOME/Documents} make effect.
  2. ~/ can be known as Home directory by Emacs, typing C+ x + f, and ~/ , All Emacs(s) in devices point to the right Home Directory.

  • AFAIK, this is not an Emacs issue but a LaTeX issue. Note that $HOME works for me in a WSL-Ubuntu environment.

  • Wow, in my case, $HOME also works when I use a non-Emacs editor.

    What is the value of M-x getenv <RET> HOME <RET>? If HOME is not in the environment of Emacs it cannot be passed to LaTeX. But, that case would be rather strange.

    The slash at the end of HOME is bad. Run M-x setenv <RET> HOME <RET> /Users/abel <RET> and try again.

    Under Linux I would now advise you to fix the HOME path in your /etc/passwd file. But, I do not know whether this advice is valid for MacOS. A hacky solution would be (setenv "HOME" (directory-file-name (getenv "HOME")) in your init file. I assume that is approximately what TeXShop does before running LaTeX.
